 John and Joan Tilley died sometime in the winter of 1620/1621, possibly after coming ashore, per Bradford, to the new Plymouth settlement.They were buried in Coles Hill Burial Ground in Plymouth, most likely in unmarked graves as with so many who died in that first winter.Their names, along with others who perished that winter, are memorialised on the Pilgrim Memorial Tomb on Coles Hill as "John Tilley and his wife."
